Muon $g-2$: A review

Abstract

The muon magnetic anomaly, $a_{\mu }=(g_{\mu }-2)/2$, plays a special role in the history of the Standard Model (SM). Precise calculations and measurements of this fundamental quantity provide a stringent test of the SM and a window to the physics beyond. In light of the first result published by the Fermilab Muon $g-2$ experiment, this article reviews the current status of the experimental measurement and theoretical prediction of the muon anomalous magnetic moment. It also provides an overview on resulting constraints of associated physics beyond the SM (BSM), future muon $g-2$ experiments, and on the progress of experiments that are closely connected to the physics of the muon $g-2$, such as measurements that could provide complementary information about BSM physics in the muon sector.
